The 44-39420 lift kit utilizes the very best in ReadyLIFT engineering with boxed steel front/rear cross members and full-width front skid plate constructed of thick 3/16" plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting.



Our 4" lift kit features heavy-duty angled and offset top mount strut extensions that realigns the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better handle the larger wheels and tires that will find their way onto this new lifted truck. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings have been added as well as new rear shock extensions.



With months of engineering and development and more awesome features than we could possibly mention, the bottom line is this new Big Lift Kit is the best 4" lift kit you can install on a new body style 2019-2024 GM 1500 4WD truck! Thousands of miles of road and trail testing have proven our new 4" lift kit makes these new GM 1500 trucks ride better than stock!

TIRE FITMENT

44-39420 4" Lift Kit - Recommended max tire with no trimming: 20x9 0 offset - 35x12.50 tire. *Max with trimming: 20x10 -18 offset - 35x12.50 or 325/60R20 *Trimming requirements for larger than recommended wheel/tire include front valance, front felt liner edge, rear felt liner edge and front rear well edge mud flap.





Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.

Best Guide Ever!
Format: Hardcover
Comic Book Guy's book of pop culture is a hilarious read. Get in the know with Film, sci-fi, gaming, and of course, comics. Read all about a typical day in the life of comic book guy and learn his all time favorite quotes. Take a look at how to run your own comic book shop. Look at CBG places to be such as gaming tournaments, parent's basement, and baseball card convention. Learn the 15 types of moviegoers. A roll-on-the-floor-laughing book for not only for Simpson's fans but comic book fans as well. I highly, highly recommend it.

Absolutely thrilling and entertaining! Never wanted to put this book down 🫶🏻
Format: Paperback, Format: Paperback
I’m not gonna lie, I saw this was from Jennifer Lynn Barnes, read the description, and I was immediately hooked. Search and rescue dogs? Check. Family secrets? Check. A thrilling read? Check, check, and check. I absolutely loved every minute of this book, but considering that Jennifer Lynn Barnes also wrote The Inheritance Games, I shouldn’t have been surprised. So, plot, characters, and writing. For one, with the plot, I saw a lot of reviews complaining about the open ending. I didn’t find it that open in my opinion. I think it left just enough to let you know that people’s stories don’t end just because an event does. It’s more realistic that way and I seriously don’t understand why people get so mad about it. Besides that complaint from other people (not from me), every bit of the plot was exciting in this book. As far as the characters go, if you love love love Jameson from The Inheritance Games, you’ll absolutely adore Jude. Same character type and everything. Kira was obviously very reserved and different as a person because of her trauma, but I liked her depth. I wish we would’ve gotten a little more backstory about what happened to her in the woods and why it happened, but that’s okay. And the dogs? Probably the best characters in the whole book. Lastly, with the writing, if you liked any of Jennifer Lynn Barnes’ previous books, you’ll love this one. I seriously enjoyed this book so much. Overall, this was a book that I couldn’t put down and literally kept me on my toes. One hundred percent worth it to read (unless you don’t like somewhat open endings). Definitely a top read for this year. Favorite quote: “The things that haunt us, they make us human.”

This was a lovely story!!
Format: Kindle
I really enjoyed The Lovely and the Lost, all the characters were really vibrant and unique. Kira was found lost in the woods when she was a little girl. No one knew how long she had been on her own in the woods. Cady Bennett, the woman who had found her, adopted Kira and raised her with Jude, her son. Together Jude, Kira, and Free (their closest friend) train with their dogs to become search and rescuers. Now teenagers, they go on their first mission. It is hardest on Kira, who sees parallels between herself and the missing girl. Secrets start popping up and exploding, things are getting dangerous, and Kira is more determined than ever to find the lost child and bring her home. The story was heartwarming, adventurous, and had many laugh out loud moments. The end left a hint of an mystery uncovered, so a sequel would be greatly appreciated! Well done!
